Resolution of 3840 × 2160 pixels — four times higher than Full HD. In hotels, 4K requires: TV with HEVC decoder, 4K-capable headend, minimum 25 Mb/s per stream and HDMI 2.0 cable. Without all conditions met, guests see Full HD even on a "4K" TV.
Device creating a wireless WiFi cell in the building. In hotels, each corridor or few rooms is served by a dedicated ceiling-mounted AP. Correct AP placement determines coverage, throughput and elimination of dead zones. Powered via PoE.
iBeeQ's hotel technology infrastructure management system. Handles Vestel CMS TVs, IPTV channel management, device lockouts and network diagnostics. Enables remote changes without entering rooms, with full PMS integration.
Login page displayed to guests upon first WiFi connection. May require a code from reception, terms acceptance or social login. Lets the hotel collect GDPR consent, limit bandwidth and personalise the welcome.
Feature enabling playback of TV programmes from the last 7 days (sometimes up to 30). Hotel guests can watch a missed programme without external VOD services. Requires a catch-up server integrated with the headend or IPTV operator.
Google technology enabling guests to cast content from their own smartphone or laptop to the room TV — without logging into any service on the hotel device. Guest data never reaches the TV.
Common Interface Plus — standard conditional access module (CAM) used in TVs. Enables reception of encrypted premium channels (e.g. Sky, Canal+) by inserting an access card into the CI+ slot.
Philips hotel TV management system (CMND & Control, CMND & Create, CMND & Check-in). Enables remote cloning of settings, creation of guest portals and automated check-in on TV.
Vestel hotel TV management platform. Offers remote fleet management, personalised guest portal creation, PMS integration and channel list management. Used in Vestel and related brands (Finlux, Telefunken).
Digital Video Broadcasting — Cable. Standard for distributing digital TV over cable networks (CATV/MATV). Used in hotel internal distribution systems fed from a local headend.
Digital Video Broadcasting — Satellite 2nd generation. Standard for receiving satellite signal. Used in SMATV systems as the source signal for hotels outside cable network coverage areas.
Second standard of terrestrial digital TV (DVB-T2) with HEVC (H.265) compression. Mandatory in Central Europe — TVs manufactured before 2018 without DVB-T2/HEVC decoder cannot receive terrestrial signal.
An encoder converts a video signal (HDMI, SDI, composite) into an IPTV or DVB-C stream. A transmodulator converts a DVB-S2 (satellite) signal into DVB-C (cable). Both are key components of every headend.
Electronic Programme Guide — on-screen TV programme guide. In IPTV systems, hotels can configure their own EPG with channel logos, programme descriptions and catch-up. Without a correct EPG, guests only see channel numbers.
Device or software controlling traffic between the hotel network and the Internet. Blocks unauthorised access, filters dangerous content and protects guest data. The first line of defence for any hotel network.
Gigabit Passive Optical Network — passive fibre FTTH network where a single fibre delivers TV, Internet and phone to each room. No active elements in risers, zero signal attenuation over 20 km.
Guest Room Management System — integrates lighting, air conditioning, blinds, TV and presence sensors in one panel or app. Automatically reduces temperature and turns off lights after guests leave, reducing energy costs. Often integrated with PMS and IPTV.
Hybrid Broadcast Broadband TV — standard combining traditional terrestrial TV with Internet content. Enables catch-up TV, apps and digital services directly from the remote — without Smart TV hardware.
Central device receiving TV signals (satellite, terrestrial, cable, IPTV) and processing them for distribution across the hotel network. Modern headends are compact and fully IP-based.
Special operating mode built into professional (hospitality) TVs. Locks settings for guests, enables welcome screen configuration, volume limitation and start channel setting. All parameters protected by a service PIN accessible only to technical staff.
Internet Group Management Protocol — manages multicast transmission on IP networks. In hotel IPTV, IGMP Snooping ensures streams are only sent to rooms watching a given channel — not flooded across the entire network. Without correct IGMP configuration, hotel IPTV does not work.
Internet Protocol Television — TV delivered over IP network instead of antenna or satellite cable. In hotels, enables interactive guest menus, VOD, property info and personalised welcome screens.
Samsung hotel TV management system. Central configuration and remote fleet management via cloud — no local server required. Supports settings cloning, firmware updates and interactive guest menu creation.
Master Antenna Television (MATV) — shared antenna system for the entire property. SMATV (Satellite MATV) adds a satellite dish. The signal from the headend is amplified and distributed to every room via coaxial network.
"One-to-many" transmission — a single source (e.g. headend) sends a stream and the network copies it only to requesting recipients. Foundation of hotel IPTV: 200 rooms watch the same channel but the stream leaves the headend only once.
Over The Top — video delivery over the public Internet, bypassing traditional cable networks (Netflix, HBO Max, Disney+). In hotels requires properly sized bandwidth and QoS management.
Property Management System — hotel management software (e.g. Opera, Protel, Sihot). PMS integration with TVs enables automatic check-in on screen, personalised welcome messages and billing services to room.
Power over Ethernet — standard for powering network devices (WiFi access points, IP cameras, VoIP phones) via UTP cable. Eliminates the need for separate power supplies at each access point in the hotel.
LG's hotel TV content management system. Enables central configuration, remote updates and interactive guest menu creation. Available in Server (local) and Cloud versions.
Quality of Service — mechanism for prioritising network traffic. In hotels, QoS ensures that video streaming and VoIP take priority over file downloads, eliminating buffering while guests watch TV.
Device connecting the hotel's local network (LAN) to the Internet (WAN). Hotel routers typically handle: VLAN, QoS, firewall, VPN for staff and Captive Portal for guest access control.
Service Set Identifier — the WiFi network name visible to users. Hotels use multiple SSIDs: separate networks for guests, staff and management devices, each with different permissions and VLAN assignments.
Device connecting devices on the local network (LAN) — servers, access points, TVs, IP cameras, VoIP phones. A managed switch enables VLAN and QoS priority configuration. Hotels typically have one main switch and one per floor.
Virtual Local Area Network — logical separation of network traffic on the hotel's physical network. Separates guest network (Internet) from TV management and device networks, improving security and performance.
Video On Demand (VOD) — any video content available on demand. SVOD (Subscription VOD) is the subscription model (Netflix, Disney+). Hotels implement internal VOD systems for guests without Smart TV requirement.
Voice over IP — telephony over IP network. Replaces analogue telephone exchanges (PBX) with digital SIP systems. Hotel room phones are increasingly VoIP devices integrated with PMS.
IEEE 802.11ax standard (WiFi 6) and its 6 GHz band extension (WiFi 6E). Handles many devices simultaneously (OFDMA) — essential in hotels where each guest brings multiple devices. Throughput up to 9.6 Gb/s.
Visual map of WiFi coverage and signal strength overlaid on the building floor plan. Colours (green → red) show where signal is strong and where dead zones exist. Result of professional WiFi surveys — essential for correct AP placement.
